Quiescent current is 1 mA typical, with a 15 mA supply maximum. On-chip protection covers over-temperature, reverse polarity, and short-circuit — three fault modes common in automotive and industrial environments where the regulator sees raw battery or unregulated DC.","metaTitle":"LM2931Z-5.0/LFT1 Texas Instruments LDO Regulator, 5V Fixed","metaDescription":"Texas Instruments LM2931Z-5.0/LFT1 is a 5V fixed-output LDO regulator rated 100 mA with 55 dB PSRR at 120 Hz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"55dB (120Hz)","Series":"-","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LM2931","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~85°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"0.3V @ 100mA","Current - Supply (Max)":"15 mA","Voltage - Output (Max)":"-","Supplier Device Package":"TO-92-3","Current - Quiescent (Iq)":"1 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a1fc1fb26b34914a47369a4f360231c6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2931Z-5.0%2FLFT1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2931Z-5.0-LFT1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2931Z-5.0-LFT1 when reusing this data.
